Circulating concentrations of prolactin (PRL) have recently
been suggested as an indicator of fatigue during exertional
heat stress, given its strong relationship with core
temperature (Tre). In addition, increased PRL secretion is associated
with the increased 5-hydroxytyptamine (serotonin)
and decreased dopamine concentrations, which define central
fatigue. However, the strength of the PRL and Tre relationship
is unknown when different rates of Tre increase are
observed. This study examined the PRL response of endurance-trained
individuals as an indicator of fatigue during
slow and fast increases in Tre.
